To all whom it may concern:-

Be it known that I, J OHN Nnsm'rn, of Lowell, in the county ofMiddles'ex and State of lllassachusetts, have invented a new and usefulMachine for the Manufacture of Wire- Netting and Wire Fence by Power;and I do hereby declare that the sameis fully and clear- 1y describedand represented in the following specification and accompanyingdrawings, letters, figures, and refercncesthereof.

'Of the sand drawings, Figure 1 denotes a .plan. Fig. 2 denotes a sideelevation. Fig. '3 denotes anelcvation of i one of the parts of mynetting-machine, which may be called the feeder. Fig. 4 is anelevationot' the other principal part of my machine, which I call thetwister. Figs. 3 and 4-show the two principal parts of the saidinachineas discournected from each other, or an inside View? or elevation ofeach partwhcu they are connected to each other.

' The principal and main lectures of novelty .of my inventiou'consist inthe principle of the revolving of the wires parallel to each other atthe same time they are being twisted, and the other parts'aud movementsof my'machine to produce theeil'ects hereinafter described.

To carry out my invention and design fully, and first to manufacture mywire-netting and wire-fence machines, it is the best plan, iu myopinion, to construct the various parts of said machines of such'materials as are hereinafter named. The frames should belof. cast-iron,.also the cams, the stands, andgearing of the same material, The levelsandshippers throughout should be of wrought-iron. The

' iaws (r G may bemade of cast-iron, to'which must be' attached pieces;of steel where the same come in contact with the wires. The net-tingbeam or cylinder vHI may be made of hard wood, with iron centers, andthe ratchetgear on said cylinder may be of cast-iron.

The center part of the wire-reels maybe made of wood, with a sheet-ironrim on flange on each side.

It will be readily understood by any good practical workman, byinspecting the inclosed drawings and specification, and following outthe details described hereinafter, how to make,

construct, and'use my wire-netting machines. It is necessary to havemachines for making every different size of thejnetting or fence-,-

that is, for every difierent size of the meshes of the sameeand anywidth ofthe netting less than the whole scope of the machine can bemade'by simply drawing in the number of v wires desired,as-willbeunderstoo'd hereinafter; and in proceeding to operate or use mynetting e. machines it will be seen by examining the drawings that thesame are composed of two parts connectedtogetherby two shafts, as seenat P and Q, Fig. 1, and one-of the said .parts I call the. twister, theframe of which The other part I g call-theflfeeder, the frame of whichcan be seenatBB,Fig.2.

" The border-wire to netting and top and betis shown at'A A, Fig. 2.

tornwire in fence is usually largerthan the wire to be twisted, althoughthe wires can all be of the same size, if desired. The wire isplaced-upon the reels 0 0, Fig. 1, and then one endofthe same is passedthrough a hole whiclrisdrilled in-the-ccnt-er of thefour cutside gears,E E andX X, Fig. 1. The said ivires are then passed to the twisting'part of the machine, and through holes drilled in the centerslof, thetwo outside twisting-gears, J J

Fig. Then the said'wire is passed between the jaws G-G, Fig. 2, and thento the cylinder H, as seen at Figs. 1 and 2, and firmly secured tothesameby a clamp, g, and a catch, which can be seen at Figs. 1 and2,-then the wires to be twisted, which are wound upon or around. thereels D D D 'D, Fig. 1. Said reels are then placed upon the stands I I II, Figs.

1 and 2, on which they revolve as the wire isbeing'drawn off from them.One end of the wire on each of the four reels D D D D isthenpassedthrough one end ,of the reelstands I I I I, Fig. 1, thence to andthrough.

the slots in the twisting-gears J J J J, Fig; 1., and then they arepassed between the jaws G G, Fig. 2, and thence to the cylinder l'i,Figs. 1 and 2, andsecur'ed to the said cylinder by the same contrirauceast-he border-wires, before described.- The said wires being all. ad-

justed, as-ab'ove mentioned, the power is applied to the'driving-pulleyK, Fig. 1, which is conveyed to the shafts 1 and Q, Fig. 1, by means ofthe shaft L and gears L and M, as

seen at Fig; 1. The shippers S S S S, Figs. 1 and 2, being first raisedby the cams R R and U U, Fig. 2, operating against or raising the.

levers T T, which are shown in Fig. 2, it being understood that theshippers'S S in the twisting part of my machine act in concert with andsimultaneously with the shippers S S in the feeding part of my machine.By this moveme'ntth'ey'arebrought into the position as shown in Fig. 2of'i'he drawings, and then stop moving, and as soon as the movement ofthe said shippers ceases the twisting-gears J J J J J, Fig.1, and thefeeding-gears E E E EE and X X X X X, as seen at Fig. 1, make tworevolutions, they revolving exactlywvith each other, so as to keep thewires parallel and from getting entangled with each other, tworevolutions of the said gears being all the twisting that is necessaryat each end of .the meshes in the netting. and fence for making goodsubstantial work, although more or less twisting of the wire may beobtained, if desired, by altering the gearing in the followingmanner-via, by enlarging the gear N, Fig. 1, if more than tworevolutions are required of the saidtwisting and feeding gears, and byreducing the gear N, Fig. 1, if less than two revolutions arc wantedinthe said'i'eedi'ng and twisting gears at each end of the meshes in thenetting;

The before-mentioned gears J J J J J and E E E E E and X XX X X,altermaking two revolutions, as before stated, cease moving;

which is efi'ected by a part of the teeth 0!. the

gear N, Fig. 1, being cut ofi' from its periphery,

and as the said twisting and feeding gears stop revolving in suchposition-that the slots in the said gears are on aline with each other,so that the wires can be shipped from one set. of gears to the others bythe shippers S S S S,

Figs. 1, 2, 3, and 4, and so that the wires can t be shipped back fromone set of gearsto the others by the shippers V V V V, Figs. 1, 2, 3,

and 4, it bcingnnderstood that the said feed- I ing and twisting gearsrevolve and stop alternately-that is, they revolve when the shippersceuse'moving, and that the shippers perform their duty while the saidgears remain motionless, and as the said gears stop revolving the jaws GG in the twisting part of my machine are -inoved backward nearly to thetwisting-gears 'J J J J J by the cant Y and arms and.connecting-piecesr, Fig.- 2, and the spring 6, Fig. 1, and by the peculiar eon structlonof the upper jaw, G, and connectingpieces 7', they (thcsaid jaws G G,Fig. 2) are brought together upon the wire and then moved forward,ortoward the cylinder H, onehalf the'lengtli of the meshes of the netting,as will readily'be understood byinspection of the drawings, and when thewire is so drawn forward and the jaws G G stop, then the shippersS S SS, Figs. 1, 2, 3, and -t-that is, onev of the two sets of shippers oneach side of the feeder-frame and one of thetwo sets of ship- ,1 pers,Figs..1 and 4, on each side of the-twisting-gears-sare first raised bythe cams R and U, said shippers then remaining in this position.untilthe wire is sulticiently twisted. Then they are depressed ormoveddownward .to their lowest position, as seen at V V V' V,

shipped from the position in which they were left by the shippersS' S SSto the other feeding and twisting gears, as will be read-' il yunderstood by inspection of the drawingsthat is, one setof shippers movethe four inside wires one way and the other set of shippers will movethe four-inside'wires'the other 'way at the required time toharmonize-with the other correct movements of themachine.

.lhe two' outside or border wires never move transversely, but movelongitudinally, like the other wires, except that they pass throughholes drilled in the center of the four outside feeding-gears and thetwo" outside twistinggears. lhe two outside small wires are wound twicearound the border'wires at every other twistingop'eration, as will beseenby inspection of Fig. 1. 4

Thereel-stands I'III, Fig. 1, have'each a spring on the side-next thereel, the object be;

from-coming OffflI-hB reel'stoo easily.

The wire for netting, -fencing, should be well annealed. The'necessityofthis will .The take-up motion to the cylinder H, Figs, ,1 and 2,1iscomposed of a ratchet-gear, h-,-Fig. .1, and cam 1', Fig. 1, and leverj,Fig. 1.

Atf, Fig. 2, is shown a shaft which supports a straight-edgc,-over whichthe wires travel as they pass through the machine.

(Z d, Fig. 2, are two movable planes that are moved or brought togetherby means of the cams Z and m, Fig. 1, and levers e and 'n, Fig.-

1, the object of the said planes being to guide the wires when they areshipped, and to hold the wires firmly while they are being twisted, sothat the wires may not be sprung where they are not twisted, and at theend of each twisting operation they (the said planes dd) open or-moveapart, but are together, as seen at d d, Fig. 1. On the top plane, d,there are five small vertical projections-one in the front of the centerof each gear. These'projections are to prevent the wire from beingtwisted'too far'into the meshes. By inspecting the drawings it will beseen that the jaws G G are made in such shape that as they are movedbackward by the cam Y and arms 0', the jaws are opened, and when theyare moving forward they are brought in contact with the wire by shuttingtogether,

by which operation the said wire is moved from one twisting operation toanother, and so on. v 'It being understood that the take-up motion actsor operates at the right time, so as to keep the wire straight andsmooth during the operation of the said machine, as hereinbefore setforth, and having thus described my invention, I will state my claims asfollows:

1. Revolving the wires bythe means, suirstantially as described, for thepurposes of keeping thern parallel to each other, so that get entangledwith eachother process of making'the netting or they cannot during thefencing.

2. Vibrating the wires alternately from the left to the right,or theright to the left, be-

fore or after or at the sameItime of twistingthemflhe said wires)together, by means of the cams R and U, the shippers S S and V V,connected to the said cams by levers T T, asseen in the drawings, orsubstantially the same, for the purposes of making wire netting andfencing.

3. Thejaws or clampsG G, or the same'in substance, for the purpose ofdrawing the wire through the machine at the required times by meaii s ofthe cams and levers operating the same, essentially as laid down in thewithin specification and drawings.

4. The two planes d d, or their mechanical equivalents, with the camsand levers for operating the same, substantially as and for the purposesset forth.

5 The wire-reels and movable reel-stands,

with the friction-springs for the reels, and

same, and the said gears having slots cut in them, for the receivlng andsliding of the ends of the stands and wiresin the same, substantially ashereinbefore set forth and specified.v
